Taxonomy of Finfish

2.3.11 Morphology and Morphometric Characters of Shark

The measurement of most of the morphometric characters are similar to bonyfish. As sharks do not have spines or rays in fins, measurements of fins should be from the origin of the fin to the respective fin lobe. The characters should be selected for sharks from the one given for bonyfishes in accordance to its morphology. Length of claspers and measurements of upper and lower lobes of caudal fin should be taken in addition to the characters listed for bonyfishes.
